Abstract
A device for measuring cycles of random reciprocal motion of an object, such as a control valve which moves in discrete movements of varying length between an opened and closed position, includes a cylindrical travel translator member biased within a housing by a coil spring to maintain tension on a cable connecting the travel translator member to the object, so that the travel translator member moves in a direction corresponding to and a distance proportional to that of the object. An elastomeric wheel frictionally engages the travel translator member to rotate a shaft which operates a mechanical counter, and through a cam, a limit switch which generates pulses representative of the random cycles of the object. Rotation of the shaft is limited to that required to operate the counter and limit switch by stops so that the elastomeric wheel slips relative to the travel translator member when the object continues, either in the same movement or in successive movements, to travel in a given direction beyond the amount required to operate the counter and limit switch.
